A look inside the Detroit Auto Show

Overwhelming crowds in Detroit this week are a clear sign the auto industry is no longer spinning its' wheels.

The North American International Auto Show is underway.

There is renewed energy and excitement that had been missing from this show and in the industry for years, fueled now as much by hope as horsepower.

"We're seeing the best sales since 2007, and we anticipate that they'll keep going up over the next few years," says Edmunds.com senior analyst Michelle Krebs.

50 new vehicles will be unveiled at the show, including the new 2014 Corvette, shown for the first time Sunday night.

"I think that will be the star of the show," Krebs says.

A close second might be the array of new luxury vehicles, which these days, come with a lot more than just leather seats.

"They are stretching the envelope," says Jake Fischer of Consumer Reports. "We are seeing smaller cars than we ever saw before - we are seeing bigger cars than we ever saw before. Every niche, everything is going to be filled. there is going to be more choices than ever for consumers."

If the response in Detroit is any indication, car buyers are in no hurry to tap the brakes.
